Thanks for this! I bought one of these and had so much trouble with it. It eventually got to where it would only connect to my PC for a second, drop, reconnect, drop, etc. I got a new one and have started with this code, and this new one is playing nice. I can now work from this :)

Oh yeah, I got that to work on the first WT32-SC01, but I'm more familiar working with Arduino, so this code let me check that all does actually work with this board and Arduino. I need to become better with ESP-IDF.

Difference between Arduino & ESP-IDF.

Finally a sketch that I could use and know that my WT32-SC01 Plus is working fine, the touch part wasn't working. Thank you for the great job.

Thanks. A full project with source is here.

Very Helpful, finally solved my problem. Thanks

Damn I can't get it to work :(

@cdctx07 I have the same problem with connecting, disconnecting, connecting ... with my Wt32 SC01 Plus. I can load the sketch, but it does not start. Is this really a problem with the HW. Have you replaced your SC01?

I was able to run another project with platform.io

Not sure if this is related? A faint memory tells me I ran into a similar issue some time ago. As far as I remember I solved the issue by lowering the upload speed.

I also had this connecting disconnecting problem but later came to know that it had selected hardware esp32_sc_01 on 8ms.xyz platform while this board is esp32_sc_01 PLUS so for PLUS version ZX3D50CE02S_USRC_4832 is to be selected. And after that when I burn the bin file with the help of esp tool, the problem is solved.

Connection/Disconnection issue is related to ESP32-S3 native USB switching.
Its better to get the debugger board from Wireless tag to make life easier.

Link for purchase is here

After pulling GPIO0 to ground, pushing the res key and releasing GPIO0 again, the download of code is perfectly working. But just a few minutes ago i found i very interesting problem: After loading the Code the screen stays dark, i can see the connect/disconnect in my syslog. Yesterday evening i stopped working with this board and today, just before, i connected the board to a USB power Supply ... and the code was running perfectly. I disconnected again and reconnected to my PC, it was working again. Then I disconnected once more and reconnected again, and now nothing happens anymore? Must i wait until tomorrow to have the code running again? Has anybody seen this problem also?
Does anybody know exactly which board to select and/or build flags to use in platformio for the WT32 SC01 plus?

@sukesh-ak

Thanks for the link, but i do not have an upload problem, as i fixed it as described in my last comment in the same manner as in the discussion in your link.
My problem is that the sketch does not start after uploading, even after powering down and up again. I must wait ~10 minutes (maybe a little bit less ) before the sketch can run.

That does not sound like a hardware issue :)

I didn't experienced this using pio

This worked great. I was about to send board back. Thank you.
